Introduction Chungnam National University (CNU), Daejeon, Korea. Distribution with an asterisk means it is a new record in this area. The genus Pseudoloxops Kirkaldy, 1905 belongs to the subfamily Orthotylinae (Hemiptera: Heteroptera: Miridae) containing 41 Taxonomic accounts species in the world (Schuh 2002e2013). Among the genus, 13 Genus Pseudoloxops Kirkaldy, 1905 홍색들장님노린재속 (신칭) species are recorded in the Palaearctic Region, six species are Pseudoloxops Kirkaldy, 1905: 268. Type species: Pseudoloxops recorded in China, and four species are recorded in Japan (Kerzhner coccineus MeyereDür, 1843. and Josifov 1999; Aukema et al 2013). In this study, the genus Aretas Distant, 1909: 450. Pseudoloxops is reported from the Korean Peninsula for the first Zonodorellus Poppius, 1915:68. time based on two species: Pseudoloxops miyatakei (Miyamoto 1969) and Pseudoloxops miyamotoi (Yasunaga 1997).
